Title: Tape cassette
Inventor: SHIMA MOTOHIKO
IPC: G11B23/087
Filed: 1995-10-13
Abstract: PROBLEM TO BE SOLVED: To prevent a reel brake mechanism from coming off even when a strong impact is applied to a case such as a drop impact and to prevent the occurrence of the slack in a tape by surely abutting a lock member on a brake releasing member thereby preventing deformation even at the time of loading the cassette into a recording and reproducing device. SOLUTION: This cassette is provided with a reel brake member 7 for suppressing rotation of a tape reel 2 as to be freely engageable with and disengageable from the tape reel 2, and a lock member 8 for regulating the reel brake member 7 in its movement in the brake releasing direction is provided on the reel brake member 7. In this case, the reel brake member 7 is constituted of a material different from the lock member 8, and since the material for the reel member 7 is particularly composed of a composite material using on either one of polyacetal resin and polypropylene resin as a base material, containing a component of elastomer 5-30wt.%, and moreover, a lubricant 1-10wt.%, this even when drop impact is applied, the brake mechanism does not come off, and the slack in the tape does not take place.
Patent JP-H02136162-A (JP)
Title: Scissors
Inventor: KATO TAKAO
IPC: B26B13/28
Filed: 1988-11-17
Abstract: PURPOSE:To prevent the loosening of a screw produced by the friction of an opening and closing motion, by using a bolt with a spiral screw on the pivot of scissors which rotatively mount a pair of nipping objects around a pivot. CONSTITUTION:A spiral groove 6 is formed in the pivot hole of a nipping object 3B and a bolt 1 with a spiral screw for a pivot is inserted through the pivot hole of a nipping object 3A. This bolt head part (a) is fixed to the nipping object 3A by a fixing plate 2 and small machine screws. The spiral groove part 6 can thus rotate around the bolt. In this way, by the working of the spiral groove 6, a contact pressure necessary for the cutting element of scissors gradually becomes stronger, as the contact point moves from the root 4 of a cutter to the top 5. On the other hand, by the working of an elastic body 7, the loosening produced by the abrasion of the cutter is absorbed. Furthermore, when the scissors is designed, it is possible to change the magnitude of the contact pressure by changing the pitch of the spiral groove.

Title: Portable terminal equipment with back light
Inventor: MASUBUCHI SHINICHI
IPC: G06F3/02
Filed: 1995-11-10
Abstract: PROBLEM TO BE SOLVED: To prevent the misoperations of a portable terminal equipment with its back lights kept turned off just by turning on the back light as the first input operation carried out to an input part while the back light kept turned off and then validating the operations of the terminal equipment from the next input operation. SOLUTION: If a user forgets to turn off the back lights 3 and 5 of a portable terminal equipment in a bright environment, both lights 3 and 5 are compulsively turned off by means of an illuminance sensor 6 for reduction of the power consumption. Furthermore, the lights 3 and 5 are automatically turned off by a timer 8 even in a dark environment when the terminal equipment is not operated for a fixed time or longer. When the user tries to perform an input operation in the automatic turn-off mode, the user is unable to identify an input part 4 and a display part 2 since the lights 3 and 5 are kept turned off. Therefore, both lights 3 and 5 are just turned on as the first input operation and no input processing is carried out so as to prevent the misoperations. When both lights 3 and 5 are turned on, the parts 4 and 2 can be correctly identified and therefore accurately operated.
